To all whom it may concern:

Be it known that I, OTTO HEINS, a subject of the Emperor of Germany, and residing at Edgewater, county of Bergen, and

This invention relates to an interrupter for ignition machines and particularly to one whose housing is mounted on a sleeve on the journal box concentric with the shaft ofithe machine and is adapted to be turned thereon to adjustthe period of ignition.

The principal object is to provide means for supporting the interrupter in either one of two positions onthe housing, whereby the rod for adjusting the period of ignition may extend to that position which is most convenient for the driver of an automobile, notwithstanding the various arrangements of other parts of the operating mechanism in the diverse types of cars.

Wherever possible the period of ignition is adjusted by hand from the drivers seat, and for that purpose there is usually provided a rod connecting the adjusting lever of the interrupter to a handle at the drivers However, the arrangement of the rod is generally difl'erent in the various'types of cars, so that the mounting of the ignition machine often involves considerable did.- culty in cases where the position of other parts have already been advantageously determined. These difiiculties are materially diminished and often entirely eliminated by providing alternative points for connecting the drivers handle withthe adjustiug'levcr of the ignition machine.

i In accordance with this invention, the interrupter housing is provided with two seats for mounting the interrupter, while the interrupter elements are so constructed that they permit either position. These seats are symmetrically disposed with respect to a median plane passing through the axis of the shaft and the point of contact betweeh the cam-disk and the interrupter lever, whereby, with the interrupter mounted on one of the seats, the period ct ignition is adof any well known type justed by connecting the rod from the drivers handle to one side of the adjusting lever, and whereas, with the interrupter mounted on the other seat the same adjustment is attained by connecting the rod to the other side of the adjusting lever.

In the accompanying drawingsiillustrating the preferred embodiment of my invention, Figure 1 is an elevation partly in section of the interrupter end of the ignition machine on section line 1.1 of Fig. 2, showing the interrupter mounted on the left hand seat of the housing; Fig. 2 is a bottom view of the interrupter housing; and Fig.3 is a.

sectional elevation of the housing with t e interrupter mounted on thevright hand seat. In the drawings, A is an i ition machine aving suitable windings to generate an ignition spark for an internal combustion engine. The inter rupter housing B surrounds one of the journal boxes of the machine, while the cam ring C is mounted on the shaft S so as to rotate with it.- The two adjusting levers D and D, are fastened to the interrupter housing B, and are provided with eyes as shown. The rod 1% extending to a handle near the drivers seat is connected in any suitable way to one of the levers D, or 1),, depending upon the position of the interrupter. By means of the adjusting rod, the driver can turn the housing through a small angle about the axis of the shaft S and thereby adjust the period of ignition. The housing is designed to have sufiicient friction against turning to hold it in any position to which it may be adjusted. I

The interrupt/er lever F is pivotally mounted on the stud E and is in electrical connection withthe frame of the apparatus. The plate spring G is fastened at one end to this lever, while its other end extends freely within the slitted block H, so that the spring constantly tends to hold the con tact terminals I and K in electrical contact with each other. The member L is mechanically "fastened to the housing but electrically insulated therefrom in any well known way. It carries the contact terminal K which may be adjusted to various positions with respect to the contact terminal I. The member L also carries the binding post M to which oneterminal of an electric circuit may be connected. The lever .15 carries the contact terminal I at one end and a block N of fiber or other suitable material at the other end in cooperation with the cam ring C, whereby upon rotation of the shaft S the lever F is turned about its pivot E as the difi'erent cam surfaces come into engagement with the block N, In this way the contact terminals 1- and K' are periodically brought together and separated to producefthe ignition spark.

In Fig. 1 the interrupter is arranged at the left of the median plane passing through the axis of the shaft and the 'block N while in Fig. 3 the interrupter is arranged on the right of that plane. The housing is constructed so as to provide for either of these arrangements byhavingthe two seats P disposed threaded holes for the reception of the screws 'for holding the member to the seat P or the seat P, as the may be, Also the binding post M maybe fastened in the member L so as to project therefrom in either direction so that it does not interfere with other parts of the ignition machine when the interrupter is mounte either seat. It, will be apparent from 1e above that the'same movement of the rod produces the same adjustment of the period of ignition whether "the rod is connected to the adjusting lever (as Fig, or D, (as in Fig. 3)

The boss 0 the seats is provided with a threaded ho. for the reception of the adjn should it be desirable adjust ignition by turning I housir of a connection at the bottom o; machine, which cas be mounted on the 7 seat depending upon of the .ot-her parts, method or": fastening boss 0 conld be used,

it is obvious'that shown may be va scope or my inve t1 condition heir parts of that the ir suitable to the c on herein 'nn cos period of cally disposed Wits noaasaa shaft S and the actuated end N of the pivoted lever F.

Having thus described my invention, what 1 claim is:

1. In combination with an ignition machine, a support having two seats, an inter,- rupter adapted to be mounted on either one of said seats and to be turned through an angle to adjust the period of ignition and ,means for turning said interrupter. ""2. In combination with an ignition machine, a housing adapted to be turned through an angle to adjust the period'of ignition and having two seats, an interrupter adapted to be mounted on either one of the saidseats and having a pair of terminal contacts, a rotatable cam ring within said housing adapted to periodically separate said contacts, and an adjusting lever operatively connected to turn said housing, whereby the period of ignition may be adjusted with theinterrupter mounted on either of said seats.

3. An interrupter for ignition machines having a rotatable cam-ring, a contact lever actuated thereby, and a housing carrying two levers extending in opposite directions and by which the housing may be turned through an angle to adjust the period of ignition,,s'aid housing having within it tworecaption spaces for the contact lever symically disposed with res ect to a meplane passing through t e axis or" roon of the cam-ring and the point oi conta between the cam-ring and thecontact lever, whereby the contact lever may be operat-ively mounted in either side of the hous- 4:. An interrupter for ignition machines' having a rotatable camring, actuated thereby, housing adapted to be turned throu "h an angle to adjust the period of ignition and having seats symmetriespect to median plane passing through ,axis of rotation of the 1 he point of contact between the contact lever, interapted to be mounted on eit one said seats, and having cooperative conterminals and an M od for urning said i n being ted to any the adwhereof I afidx my signature, we witnesses.
